Raleigh, N.C. — Vollis Simpson, a self-taught North Carolina artist famed for his whimsical, wind-powered whirligigs, has died. He was 94.

Beth Liles of Joyner's Funeral Home confirmed the death Saturday. Simpson's wife, Jean Simpson, was quoted by the Wilson Daily Times as saying that her husband died Friday in his sleep at his home in the town of Lucama.

Simpson became known for his whirligigs, wind-driven creations that stand as high as 50 feet and are constructed from recycled parts including motor fans and cotton spindles.

His whirligigs were also placed throughout downtown Wilson, where the Whirligig Festival is held each November in his honor.

In 2010, Simpson decided to sell more than 30 of his large whirligigs and more than 50 small-scale pieces to create the Vollis Simpson Whirligig Park, which will be located on Goldsboro Street.

The Vollis Simpson Whirligig Park is scheduled to open in November in Wilson, about 50 miles east of Raleigh.

Simpson's creations have also captured national attention, with buyers including a shopping center in Albuquerque, the American Visionary Art Museum in Baltimore and the American Folk Art Museum in New York City. Four of them were also put on display at the 1996 Olympics in Atlanta.

Last month, the North Carolina House approved a measure making whirligigs the state's official folk art.

The whirligigs weigh as much as 3 tons and have hundreds of moving parts. They're folk art or what's also known as outsider art, works created by someone without formal arts training.

Neither did Simpson have a formal engineering degree. But that didn't stop him from constructing a motorcycle with a bicycle and a stolen motor when he was an Air Force staff sergeant on Saipan during World War II. He also built tow trucks for moving houses.

In an interview last summer, Simpson told The Associated Press he was conflicted about the park in his honor. He said he knew he could no longer care for his creations if they stayed at home with him, but he felt lonely without them. "I just hope I live to see it," he said of the park.
